2-methylbutane, like similar molecules, exhibits the type of intermolecular force known as London dispersion forces due to its molecular structure of carbon and hydrogen atoms.
The substance 2-methylbutane exhibits the type of intermolecular forces known as London dispersion forces. These forces arise due to temporary shift in electron clouds causing temporary dipoles which induce dipoles in neighboring molecules. This is the simplest type of intermolecular forces and it can occur in all types of molecules, but is the dominant force in nonpolar and symmetrical molecules. Hydrogen bonding or dipole-induced forces do not play a role in this substance as its molecular structure of carbon and hydrogen atoms does not allow for those types of intermolecular interactions.
As the substance 2-methylbutane is a branched variant of butane, it has a slightly different structure, but this does not change the basic type of intermolecular forces present. Other similar molecules like propane and butene also exhibit similar types of intermolecular forces. Remember, intermolecular forces are not intramolecular forces which are much stronger and keep the atoms within a molecule together. Intermolecular forces are what keep molecules attached to each other which greatly effects physical properties of a substance like boiling point.

What is the [H+] after the change?
Answer:
2
Explanation:
because the fiber is a natural fiber
because the fiber has long range order
because the fiber has a refractive index greater than 1.52
because the refractive index is less than 1.52
Answer:
Because of the chemical makeup of the fiber.
Explanation:
The birefringence is the difference between the refractive index of a fiber in a direction at parallel to the fiber axis and in a direction at right angles. It is caused by asymmetric core shape for the two axes, and majorly one of the manufacturing imperfections. It helps in controlling polarization property inside the fiber.
Inevitable manufacturing imperfections in optical fiber leads to birefringence, which is one cause of pulse broadening in fiber-optic communications. Such imperfections can be geometrical (lack of circular symmetry), due to stress applied to the optical fiber and/or due to bending of the fiber.
